When a disconnection in the input wiring cannot be detected

If a disconnection in the input wiring still cannot be detected even after the actions described above are taken,
the possible cause is a failure of the input module with diagnostic functions. Please consult your local
Mitsubishi representative.

When a disconnection in the input wiring cannot be detected
correctly

When a disconnection was detected in the input wiring

Check item

Action

Check whether the I/O status indicator LED (X0 to XF) of the input module
with diagnostic functions turns on when the external input device is on.

When the LED does not turn on, the input wiring has problems.
Check whether the input wiring has been disconnected or short-circuited and
the voltage of the input signal is proper, and review the wiring.
For the rated input voltage, refer to the performance specifications described
in the following.



MELSEC iQ-R I/O Module (With Diagnostic Functions) User's Manual

(Startup)

Check whether "Input disconnection detection setting" has been set to "To
detect".

If "Input disconnection detection setting" of the target input has been set to
"Not detected", set "To detect".

Check whether a resistor for disconnection detection has been connected.

When the leakage current of the input device is 0.3mA/point or lower, connect
a bleeder resistor (resistance value as a guide: approximately 56k



) in

parallel near the input device.

Check whether the disconnection (no connection) detection current satisfies
the specifications.

Check whether the disconnection (no connection) detection current is 0.3mA
per point or less.

Check item

Action

Check whether the wiring is influenced by noise.

Check the wiring status.

Check whether a wireless communication device such as a cellular phone or
PHS (Personal Handy-phone System) is close to the programmable controller.

Use any wireless communication device such as a cellular phone or PHS
(Personal Handy-phone System) more than 25cm away in all directions from
the programmable controller.

Check item

Action

Check whether the input wiring has any problems.

Check that the voltage of the input signal is proper, and review the wiring.

Check whether the external power supply is supplied.

Check that the supply voltage to the module is within the rated range.

Check whether the wiring is influenced by noise.

Check the wiring status.
